COBB Tuning Adjustable Sway Bar Mounts are designed to allow for proper end-link alignment when using our adjustable Tubular Rear Swaybar. As you use the stiffer sway bar settings, the rear endlink is placed at a compromised angle which reduces effectiveness and increases the chance of the endlink bending. Changing the sway bar design would only change what positions compromise the rear end link angle. With the COBB Adjustable Slider Mounts in place, you can now adjust the sway bar's position with relation to the end link. This allows you to keep the end link in the most effective position relative to its pickup point on the sway bar
